FBAR Filing Guide: Deadlines, Thresholds, and How to File

If you hold financial accounts outside the United States, you may be required to file a Report of Foreign Bank and Financial Accounts (FBAR) every year. The FBAR is one of the most common — and most misunderstood — international tax obligations for US persons.

Getting this filing wrong can be extraordinarily expensive. Civil penalties start at ~$10,000 per unreported account per year, and willful violations can exceed ~$100,000 per account or 50% of the account balance — whichever is greater. This guide explains who must file, how the threshold works, when the FBAR is due, and exactly how to submit it.

What Is the FBAR?

The FBAR is a FinCEN Form 114 filed electronically with the Financial Crimes Enforcement Network (FinCEN), a bureau of the US Department of the Treasury. This is a critical distinction: the FBAR is not filed with the IRS and is not part of your tax return. It is a separate reporting obligation under the Bank Secrecy Act (BSA).

The FBAR exists to help the US government detect and prevent money laundering, tax evasion, and other financial crimes. It requires US persons to disclose their foreign financial accounts when the aggregate value exceeds a threshold amount during the calendar year.

Despite being separate from your income tax return, the IRS has been delegated enforcement authority for FBAR violations. This means the IRS can assess penalties for failure to file even though the form goes to FinCEN.

Who Must File an FBAR?

You must file an FBAR if you meet both of these conditions:

You are a US person — this includes US citizens, US residents (including green card holders), domestic entities (corporations, partnerships, LLCs, trusts, estates)
You had a financial interest in, or signature authority over, one or more foreign financial accounts with an aggregate value exceeding $10,000 at any point during the calendar year

US Person Definition

The term “US person” for FBAR purposes is broad:

US citizens (including those living permanently abroad)
US residents (including green card holders and individuals meeting the substantial presence test)
Domestic trusts and estates
US-organized entities (corporations, LLCs, partnerships)

If you hold a green card, you are a US person for FBAR purposes regardless of where you live. Dual citizens are also subject to FBAR requirements.

Financial Interest

You have a “financial interest” in a foreign account if:

You are the owner of record or hold legal title
The owner of record is your agent or representative
The owner is a corporation in which you own more than 50% of the voting power or equity
The owner is a partnership in which you own more than 50% of the profits
The owner is a trust in which you are a beneficiary with a greater than 50% interest or from which you receive income
You have any other relationship that provides the benefits of ownership

Signature Authority

Even if you have no financial interest, you must report accounts over which you have signature authority — meaning you can control the disposition of assets by direct communication with the financial institution. This commonly applies to:

Corporate officers with authority over company foreign bank accounts
Employees authorized to sign on employer foreign accounts
Trustees with authority over trust foreign accounts

There are exemptions for officers and employees of certain regulated entities (banks, registered securities dealers, certain listed companies), but these exemptions are narrow.

The $10,000 Aggregate Threshold

The FBAR filing threshold is $10,000 in aggregate — meaning you add up the maximum values of all your foreign financial accounts during the year. This is where many people make mistakes.

How Aggregation Works

Suppose you have three foreign accounts:

Account	Maximum Balance During Year
UK checking account	$4,500
Canadian savings account	$3,200
Swiss investment account	$3,800
Aggregate total	$11,500

Even though no single account exceeded $10,000, the aggregate total did. All three accounts must be reported on the FBAR.

Key Rules for the Threshold

Maximum value at any point — not the year-end balance or average balance. If an account briefly held $15,000 in March but dropped to $2,000 by December, the $15,000 counts
All foreign accounts — checking, savings, investment, securities, mutual funds, debit card accounts, and certain insurance policies with cash value
Convert to USD — use the Treasury Department’s end-of-year exchange rate for converting foreign currency balances
Joint accounts — each person with a financial interest must report the full value (not their proportionate share)
If the threshold is met, report everything — you cannot selectively report only the accounts that pushed you over $10,000. Every foreign account must be listed

What Counts as a Foreign Financial Account?

Included	Not Included
Bank accounts (checking, savings)	Accounts held at US military banking facilities
Securities accounts (brokerage)	Correspondent/nostro accounts
Mutual fund accounts	Accounts held with US institutions, even if denominated in foreign currency
Commodity futures accounts	Real estate held directly (not through an account)
Insurance policies with cash value	Precious metals held directly
Debit/prepaid card accounts

FBAR Deadlines

The FBAR deadline mirrors the federal income tax deadline:

April 15 — FBAR filing deadline for the prior calendar year
October 15 — Automatic extension (no form or request needed)

Unlike a tax return extension, the FBAR extension to October 15 is completely automatic. You do not need to file Form 4868 or any other request. If you miss the April 15 deadline, you still have until October 15 without penalty.

For Americans living abroad who receive the automatic 2-month extension for their tax return (to June 15), the FBAR has its own separate automatic extension to October 15 regardless of where you live.

How to File the FBAR (Step by Step)

The FBAR must be filed electronically through FinCEN’s BSA E-Filing System. Paper filing is not accepted (with a narrow exception for hardship cases requiring approval).

Step 1: Gather Account Information

For each foreign financial account, you need:

Name on the account
Account number
Name and address of the foreign financial institution
Type of account (bank, securities, other)
Maximum account value during the calendar year (in US dollars)
Country where the account is maintained

Step 2: Access BSA E-Filing

Go to the BSA E-Filing website (bsaefiling.fincen.treas.gov). You can file as an individual without creating an account by using the “file FBAR” option directly, or you can create a BSA E-Filing account for saved records and confirmation tracking.

Step 3: Complete FinCEN Form 114

The online form walks you through several sections:

Filer information — your name, SSN/ITIN, date of birth, address
Account information — repeated for each foreign account
Joint accounts — indicate if the account is jointly owned
Consolidated reports — if filing for an entity, you can consolidate certain accounts

Step 4: Sign and Submit

If filing individually, you sign electronically on the BSA E-Filing system. If a third party (such as a tax preparer) files on your behalf, you must authorize them using FinCEN Form 114a (Record of Authorization to Electronically File FBARs). The 114a is not submitted to FinCEN but must be retained for your records.

Step 5: Save Your Confirmation

After submission, save the confirmation page and BSA identifier number. FinCEN recommends retaining FBAR records for five years from the filing deadline.

Joint Account Filing Rules

If spouses jointly own all foreign accounts, special rules apply:

One spouse can file a single FBAR listing all jointly owned accounts, but only if:
- All accounts are jointly owned
- The filing spouse reports all accounts
- Both spouses sign the FBAR (FinCEN Form 114a authorization)
If either spouse has a separately owned account, both spouses must file their own FBAR

In practice, many married couples each file their own FBAR to avoid complications, especially when one spouse also has individually held accounts.

FBAR Penalties

FBAR penalties are severe and can be assessed per account, per year.

Non-Willful Violations

Penalty	Amount
Per unreported account, per year	Up to ~$10,000
Reasonable cause defense	Available — no penalty if you can show reasonable cause and the violation was not due to willful neglect

Willful Violations

Penalty	Amount
Per unreported account, per year	Greater of ~$100,000 or 50% of account balance at time of violation
Criminal penalties	Up to $250,000 fine and/or 5 years imprisonment
Combined civil + criminal	Both can apply simultaneously

What Constitutes “Willful”?

Courts have interpreted “willful” broadly. It does not require intentional tax evasion. It can include:

Willful blindness — deliberately avoiding learning about the filing requirement
Reckless disregard — signing a tax return that asks about foreign accounts (Schedule B, Part III) and answering “No” when you have foreign accounts
Knowing violation — being aware of the requirement and choosing not to file

The Schedule B question on your Form 1040 asks: “At any time during [the tax year], did you have a financial interest in or a signature authority over a financial account in a foreign country?” Answering “No” when you have foreign accounts is strong evidence of willfulness.

Penalty Mitigation

If you have unreported foreign accounts from prior years, the IRS Streamlined Filing Compliance Procedures offer a path to come into compliance with reduced or eliminated penalties. Do not ignore past non-filing — the penalties grow every year.

FBAR vs. FATCA (Form 8938)

Many taxpayers confuse the FBAR with FATCA reporting on Form 8938. These are separate obligations with different rules:

Feature	FBAR (FinCEN 114)	FATCA (Form 8938)
Filed with	FinCEN (Treasury)	IRS (with tax return)
Threshold	$10,000 aggregate	$50,000–$200,000+ (varies)
Deadline	April 15 (auto-extend to Oct 15)	Tax return due date (with extensions)
Filing method	BSA E-Filing System	Attached to Form 1040
Penalty per violation	Up to ~$10,000 (non-willful)	Up to ~$10,000 (plus up to ~$60,000 for continued failure)

You may need to file both. The thresholds and covered assets differ, so it is entirely possible to owe one filing but not the other, or both. For a detailed comparison, see FBAR vs FATCA (Form 8938): Side-by-Side Comparison.

Common FBAR Mistakes

1. Reporting Year-End Balances Instead of Maximum Value

The FBAR requires the maximum value during the calendar year, not the December 31 balance. Review monthly statements to find the highest balance.

2. Forgetting About Accounts With Small Balances

If the aggregate of all accounts exceeds $10,000, every account must be reported — even one with a $50 balance.

3. Ignoring Accounts You Have Signature Authority Over

Company accounts, family accounts, or accounts for organizations where you can authorize transactions all count.

4. Not Filing Because You Owe No US Tax

The FBAR is an information return. It exists regardless of whether you owe taxes. Even if the Foreign Earned Income Exclusion eliminates your US tax liability, you still must file the FBAR.

5. Filing the FBAR With Your Tax Return

The FBAR is not mailed to the IRS or attached to your Form 1040. It must be filed separately through the BSA E-Filing System.

Frequently Asked Questions

Do I need to file an FBAR if I live in the US?

Yes. The FBAR requirement applies to all US persons regardless of where they live. If you have foreign accounts exceeding $10,000 in aggregate, you must file.

What if my accounts are in my spouse’s name?

If you have no financial interest in or signature authority over the account, you generally do not need to report it. However, if the account is jointly held or you have access to it, it must be reported.

Is a foreign retirement account reportable?

Generally yes. Foreign pension plans, provident funds, and retirement accounts are usually reportable on the FBAR. Some tax treaties may affect the tax treatment of these accounts, but they typically still require FBAR reporting.

What if I closed a foreign account during the year?

If the account was open at any point during the year and the aggregate of all your accounts exceeded $10,000, the closed account must still be reported. Use the maximum value before closure.

Can I file the FBAR late without penalty?

If you file by the automatic October 15 extension, there is no late penalty. If you are past that deadline, penalties may apply, though reasonable cause may be a defense. Consider the Streamlined Filing Compliance program for multiple years of non-filing.

Does cryptocurrency in a foreign exchange count?

This remains an evolving area. FinCEN proposed regulations that would include virtual currency accounts at foreign exchanges. As of the 2025 filing year, FinCEN has suspended the requirement to report virtual currency on the FBAR while regulations are finalized. Check the latest FinCEN guidance before filing.
